Abstract

The aim was to describe epidemiological, clinical and histological aspects of parasitic lesions caused by Stephanofilariasis on the udder of nursing cows and to evaluate the viability of a therapeutic protocol. Forty lactating cows with characteristic Stephanofilariasis lesions were divided into two groups, GI and GII. The wounds on the udder of the GI cows were cleansed with sodium hydrochloride and treated topically with an ointment consisting of trichlorphone, ivermectine, dexamethasone, calendula, zinc oxide and an adherent ointment of sodium vaseline, associated with the parenteral application of 1% ivermectine. GII served as control group and was left untreated. Twelve cows (60%) of GI had recovered on the 45th day of treatment and 8 cows (40%) showed clinical cure within 45-60 days. The diagnosis of Stephanofilaria stilesi infection is generally presumptive. Epidemiologically-related aspects, clinical findings and positive response to treatment help to confirm the disease. Histopathological exams also assist in the diagnosis when the presence of nematodes can be revealed, although this finding is not frequent. The therapeutic protocol employed proved to be economically viable and efficient, with recovery of all the lesions.
